BOWLING PIN.

Application filed flctober 17, 1927. Serial No. 228.840.

to inmrovements in My invention relates y) ogects thereot bowling pins and imporhn are to provic'ie a more subs having a pro'tect l .file indu bedded in its bottom that is spaced from peripheral er of the latter, and which embodies an ind Lni ate tnbular sleeve that is 'Light ly toreed into the center oi" the pir bottom ferming' a protecting wail about the spotter cavity and also sccurely Wedging and looking; the annulus in the pin bottom.

Further objects of the invention are to pre-4 vide a bowling pin of the charaeter dcseribeth which is simple in its constii tion and in rangement, strong durable and etticient in its use, and comparatvely inexpensive to manufacture.

iVith the foregoing and other objects in view Which will appear as the desc 'iption proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention hereinafter disclosed can be made within 'the scope of what is claimed Without departing from the spirit of the invcntion.

In the drawing wherein like numerals of references designate corresponding parts throughout the several views Z Figure 1 is a side elevational 'view of a bowling pin partly 'in scctioin constructcd in accordamee with the invcntion.

Figure 2 is a bottom plan view of tlw bowling pin,

Referring in detail to the drawing 1 denotes the body portion of a bowling pin ef conventional Configuration including: the usual reduced flat base or bottom 52.

The bottom 2 of the body porti i l :formed With a centrally di posed, i 'ertieally extendiug' bore 3, into Which a tnbnlar sleeve 4: is fixedly driven. It will o'i' course, be obvious that the letter may be fixedly Screwed or cemented in position in the bore 3, it dcsired. The sleeve 4 provides a protected Cavity 'for the centering pins, which are now commonly employed for positioning the bowling pins On their respective spots on the bowling alley. The bore 3 is formed with a flared low er .end 5 which is complemented by the flared lower end 6 of the tubular sleeve 4: and provided for the purpose of faciltating the engagcment of the centering pins With the sleeve cavities during the bowling pin setting operation.

The bottom 2 of the body portion ther formed with an annular groove 7 dsposed p'araliel relatively to the ver axis of the body portion 1, The oz. er side Wall of the groove 7 is spaced from the peripheral edge of the bottom 2, and the inner side Wall thereof is spaced from the peripheral edge et the flared lower end 5, ol? the bore 3. An annnlus 8 is securely fixcd in the a nnular groove 7, and has its lower taec disposcd flush with, the'plane su L'ace O' the bottom 2.

The annnlns 8 and the tubular sleeve l are constrncted from any suitable indurate material preferably fibre, hard rubber, or a Com- 8 is driven to position in the groove 3 and is further secured by a Wedging action e''ected thereagainst When the tubular sleeve 4; is driven to position in the bore 3.

The provsion of the annulus 8 will prevent splitting of the base of the bowling pins and provides a substantial and durable bottom that Will minimize the expense attached to the maintenance of the boWling pins equipped thereWith.

In spacing the peripheral edge of the pin bottom 2 from the annulus 8, a bottom circle of pin wood is provided Which' protects the Other bowling pins, balls, alleys, ctc., from excessive damage, due to coming into forceful contact With the indurate annulus 8, as the bowling pins are knocked about by the bowler. Further, 'this arrangement of the annulus 8 establishes a peripheral bottom margin that will not be battercd away by use, thereby eliminating' the possibility of loosening the annulus 8 in its groove 7, 'from such cause.

By maintaining the bored wood center portion of: the pin bottom 2, the whole bottom assembly Oli' the bowling pin is securely and permanently looked together by driving the annulus 8 to position in the groove 7, and by subscquently thereto driving the tubular sleeve t to position in the bore 3, for the purposition of analogous hardness. The annulus pose herein before stated.

It Will here be noted that a feature of the invention is the dependence of the annulus 8 and the tubular sleeve 4, relatively to each other. While the annulus 8 primarily pro- Vides a re-inforced pin base Or bottom 2, it will also prevent the splitting of the body portion 1 When the tubular sleeve 4 is driven to its position in the hore 8. In turn, the driving of the tuhular sleeve i into the bore 3, effects a Wedging action Whereby the annulus 8 is fixedly locked in position in its groove 7.

The present invention provides a howling pin construction that is serviceahle and continuously e'licient and enduring under the se- Vere usage custoniary Witl deviccs et its kind.

What claim is 1. ln combination, a pino? the character described having its base provided With a centrally disposed Vertically extending here and With an annular groove di sposed par llel relatively to the Vertical axis of the howlingg pin, said bore having a flared lower end, an annulus of indurate material mounted in said groove and having its lower end disposed 'lush With said base, the inner Wall of said annular groove being spaccd from the lower peripheral edge of said flared end of said bore said base lizwingg; its peripheral edge spaced from the lower end of the outer Wall of said annnlar groove, and a tuhular sleeve reaese of indurate material fiXed in said bore providing a re-enforced Centerng pin cavty.

2. ln combination, a pin of the character described having its base provided With a centrally disposed Vertically extending bore and With an annular groove disposed parallel relatively to the Vertical aXis of the bowling pm, said here having a flared lower end, an anniilns of indurate material mounted in said groove and having its lower end disposed :flush With said has-e, the inner Wall of said annular grein 'e being spaced from the lower peripheral edge of said fiared end of said here, said base having its Deripheral edge SptCGCl from the lower end of the outer Wall ei' said annalar groove, and a tubular sleeve ol indnrate material fiXed in said bore providing a re-en'forced center-ing pin cavityand t ier establishing a Wedging action for inaintaining said annulus in position in said groove.
